In this episode of The Car Doctor, Ron Ananian takes calls from real drivers facing real dilemmas. Debbie from Wisconsin wonders if it’s finally time to replace her trusty 2005 Ford Explorer — and Ron walks her through the pros and cons of keeping an aging SUV versus buying a costly modern crossover. From certified pre-owned tips to Wrangler warnings, it’s a masterclass in practical car buying advice.

Later, John in Maine tracks down a pesky P0480 code after replacing the cooling fan in his Jeep Grand Cherokee. Ron dives into wiring diagrams, OE vs. aftermarket parts, and even post-collision troubleshooting.

Finally, Paul from Virginia asks why there are so many kinds of antifreeze — and whether the "universal" stuff is actually safe. Ron breaks it down with an easy-to-follow answer rooted in engineering, not marketing.

Have an aging ride or a mystery code of your own? Tune in, learn something, and maybe save yourself a bundle.
